Abstract: PURPOSE:To prevent the deterioration of the purification efficiency of a catalytic converter by shifting the standard value of the second air-fuel ratio detecting means to the lean side of air-fuel ratio in a specific operation state, when the air-fuel ratio control is applied with correction on the basis of the result of the comparison between the detection value and the standard value of the second air-fuel ratio detecting means having the relatively low detection response speed. CONSTITUTION:The first and second air-fuel ratio detecting means 17 and 18 are installed on the upstream and downstream sides of a catalytic converter in an exhaust passage, and the air-fuel ratio correction coefficient is determined by a determining means 47 on the basis of the output of a comparison means 46 for comparing the detection value of the first air-fuel ratio detecting means 17 and the comparison standard value by a setting means 45. Further, the air-fuel ratio control by an air-fuel ratio control means 48 consisting of the means 45-47 is applied with correction by a correcting means 49 on the basis of the output of a comparison means 53 for comparing the detection value of the second air-fuel ratio detecting means 18 and the standard value by a setting means 49A. In this case, if the low speed low load operation is detected by a detecting means 50, the second setting means 49B is selected a selecting means 49C, and the second standard value which is shifted to the lean side is supplied into the comparing means 53.

Title: Desiliconization method for molten iron
Inventor: NAKAMURA HIROMI
IPC: C21C1/04
Filed: 1980-11-28
Abstract: PURPOSE: To remove the Si contents in molten iron efficiently in the state of suppressing the occurrence of de-Mn reaction by adding various kinds of CaO contents into the molten iron and controlling the basicity in formed slag to a specific range.  
     CONSTITUTION: CaO contents such as calcined lime, quicklime, light-burned dolomite and the like are added into molten iron to control the basicity (CaO/ SiO 2 ) of the formed slag to 0.5W1.5. As a result, the activity of Fe x O y  in the slag is increased, T.Fe are reduced and the reaction of (Fe x O y +Mn→MnO+Fe)  is suppressed. Hence, the dissipation of the Fe contents and Mn contents in the molten iron into the slag is prevented, and the T.Fe and MnO in the slag are lowered, thus the desiliconization treatment is accomplished effectively.
